We report the first use of direct detection for recording electron backscatter diffraction patterns. We demonstrate the following advantages of direct detection: the resolution in the patterns is such that higher order features are visible; patterns can be recorded at beam energies below those at which conventional detectors usefully operate; high precision in cross-correlation based pattern sh...

X-ray micro-diffraction profiles using a synchrotron light source were analyzed via Fourier transformation for single crystal Aluminum and Copper samples subjected to micro-scale laser shock peening. Specifically, the asymmetric and broadened diffraction profiles registered across the shock peen region were observed and analyzed by classic Warren and Averbach (W–A) method [Warren, B.E., Averbac...

The evolutions of microstructure and texture the corrosion behaviour low light rare-earth containing Mg-1.4Nd heavy Mg-0.6Gd Mg-0.4Dy (wt.%) were evaluated compared after processing by high-pressure torsion (HPT) isochronal annealing at 250 450 °C for 1 h using electron backscatter diffraction (EBSD) electrochemical tests in a 3.5% NaCl solution. EBSD results show that dynamic recrystallisation...

Abstract Mapping grain orientation in crystalline solids is essential to investigate the relationships between local microstructure and crystallography interpret materials properties. One of main techniques used perform these studies electron backscatter diffraction (EBSD). Due limited measurement throughput, however, EBSD not suitable for characterizing samples with long-range heterogeneity, n...

This work deals with the influence of gallium addition on constitution and formation phases in Al-rich corner Al–Mn system during casting. binary ternary Al–Mn–Ga alloys were cast into a copper mould cavity diameter 5 mm. The microstructures produced characterized by scanning electron microscopy, energy dispersive X-ray spectroscopy, backscatter diffraction diffraction. characterization reveale...

Within the last decade, silicon drift detectors (SDD) systems have become more and more popular in the field of energy-dispersive spectroscopy (EDS). The main characteristic of the SDDs is their extremely high pulse load capacity of up to 750,000 counts per second at good or reasonable energy resolution (<123 eV Mn-Kα, <46 eV C-Kα at 100,000 cps). These properties in conjunction with electron b...

Electron backscatter diffraction (EBSD) was applied to investigate the superplastic behavior of a fine-grain Al-Mg-Li alloy. It found that microstructural changes were noticeably influenced by occurrence continuous dynamic recrystallization. This mechanism involved transverse subdivision pre-elongated grains which eventually transformed into chains nearly-equiaxed grains. A body experimental ob...

The effect of grain boundaries (GBs), in particular twin boundaries (TBs), on CdTe polycrystalline thin films is studied by conductive atomic force microscopy (C-AFM), electron-beam-induced current (EBIC), scanning Kelvin probe microscopy (SKPM), electron backscatter diffraction (EBSD), and scanning transmission electron microscopy (STEM). Four types of CdTe grains with various densities of {11...

Registering experimental and simulated electron diffraction patterns is increasingly used for advanced backscatter indexation (EBSD) analysis, yet the accuracy of registration limited by several effects not accounted in pattern simulation, such as Kikuchi band (K-band) asymmetry, gray level reversal (mainly radial) optical distortion. Radial distortion parameters have previously been measured w...

The volume increase and shape change during austenite to martensite transformation in dual-phase (DP) steels are largely accommodated the microstructure by deformation of surrounding ferrite matrix. Accurate estimation transformation-induced via experiments modeling is essential for predicting subsequent mechanical behavior DP steels. This study aims illustrate disadvantages simplifying anisotr...
